Evaluation of chicory seeds maturity by chlorophyll fluorescence imaging

Chicory (Cichorium intybus L.) seed production includes sorting to remove foreign materials and non-viable seeds. A machine vision system was developed to monitor the fluorescence in order to detect the immature chicory seeds. It comprised a monochromatic light source, a highpass filter and a monochromatic CCD camera sensitive to red and infrared. With this device, blue light reflected by the seeds was blocked whilst red fluorescence was measured by the camera. A segmentation algorithm was designed to estimate separately the fluorescence intensities of the pappus, a crown of scales, and the main body of the pericarp. Experiments were carried out on five clones of cross-pollinated chicory plants used for seed production. Two hundred flower heads were labelled at flowering and harvested at different times during the maturation process expressed in “days after flowering” (DAF). Germination tests were performed according to the recommendations of the International Seed Testing Association to measure the germination percentage (GP) and the germination rate (GR), an indicator of seed vigour. Seed chlorophyll content diminished during maturation following a different logistic trend for the pappus and the pericarp. The GP increased from 18 DAF to reach its maximum value at 21 DAF, but the GR remained low until 30 DAF and increased afterwards. The potential of chlorophyll fluorescence to be used as an indicator of chicory seed vigour was the greatest between 21 and 36 DAF

Do We Need a World Health Insurance to Realise the Right to Health?

There has been growing recognition in the international community that health should be considered a human right. Much less attention has been paid, however, to the ensuing legal obligation to provide international assistance

Financing the Millennium Development Goals for health and beyond: sustaining the 'Big Push'

Many of the Millennium Development Goals are not being achieved in the world's poorest countries, yet only five years remain until the target date. The financing of these Goals is not merely insufficient; current evidence indicates that the temporary nature of the financing, as well as challenges to coordinating its delivery and directing it to the most needy recipients, hinder achievement of the Goals in countries that may benefit most. Traditional approaches to providing development assistance for health have not been able to address both prevalent and emergent public health challenges captured in the Goals; these challenges demand sustained forms of financial redistribution through a coordinated mechanism. A global social health protection fund is proposed to address recurring failures in the modern aid distribution mechanism. Such a Fund could use established and effective strategies for aid delivery to mitigate many financial problems currently undermining the Millennium Development Goals initiative

Towards a coherent global framework for health financing: recommendations and recent developments

The articles in this special issue have demonstrated how unprecedented transitions have come with both challenges and opportunities for health financing. Against the background of these challenges and opportunities, the Working Group on Health Financing at the Chatham House Centre on Global Health Security laid out, in 2014, a set of policy responses encapsulated in 20 recommendations for how to make progress towards a coherent global framework for health financing. These recommendations pertain to domestic financing of national health systems, global public goods for health, external financing for national health systems and the cross-cutting issues of accountability and agreement on a new global framework. Since the Working Group concluded its work, multiple events have reinforced the group’s recommendations. Among these are the agreement on the Addis Ababa Action Agenda, the adoption of the Sustainable Development Goals, the outbreak of Ebola in West Africa and the release of the Panama Papers. These events also represent new stepping stones towards a new global framework

A Global Social Support System: What the International Community Could Learn From the United States’ National Basketball Association’s Scheme for Redistribution of New Talent

If global trade were fair, it is argued, then international aid would be unnecessary and inequalities inherent to the economic system would be justifiable. Here, we argue that while global trade is unfair, in part because richer countries set the rules, we believe that additional interventions must go beyond trade regulation and short-term aid to redress inequalities among countries that will persist and possibly worsen in spite of such measures. Drawing on an example of measures taken to redress the characteristics of a system that inherently increases inequality, the ability of dominant teams in the National Basketball Association (NBA) to recruit the most talented players, we argue that market-based competition even in the context of fair rules will create and amplify economic inequalities. We argue that, just as the NBA created a draft to reduce the emergence of severe inequalities among teams, systems of social support within richer countries should be paralleled by a global system to counterbalance persisting inequalities among countries that are produced by market forces. We explain how such a mechanism might operate among integrated market economies, and identify the Global Fund to Fight AIDS, Tuberculosis and Malaria ( the Global Fund) as an example of such an emerging form of global social support

The Joint Action and Learning Initiative: Towards a Global Agreement on National and Global Responsibilities for Health

Lawrence Gostin and colleagues discuss their work on the Joint Action and Learning Initiative on National and Global Responsibilities for Health (JALI), which aims to secure a global health agreement (such as a Framework Convention on Global Health) that would inform post-Millennium Development Goal global health commitments

Universal health coverage: a quest for all countries but under threat in some.

Over the past 50 years, health care has been making a growing contribution to population health in many countries. Yet its benefits are still denied to many people worldwide. This article describes how many countries, both developed and developing, have pursued the quest to achieve universal health care. This has been an explicitly political process. In Europe, it emerged from a belief in solidarity, a fear of revolution, and a changing view of the role of the state. In developing countries, progress was more erratic, characterized by debates about the affordability of universal health care, until it was realized that functioning health systems were essential to deliver development goals. Throughout, the United States has been an exception. An analysis of progress toward universal health care, combining a review of existing theories and new empirical analysis, identifies five factors as important: the strength of organized labor and left-wing parties, adequate economic resources, absence of societal divisions, weakness of institutions that might oppose it (such as organized medicine), and windows of opportunity. Having noted the substantial benefits accruing from universal health care, the article concludes with an analysis of how universal health care is under threat in some European countries and a warning about the risks posed by current radical austerity policies
